WATCH PENDANT.

Application filed April 9, 1927.

This invention aims to provide a novel pendant for a watch, so constructed that the stem may bemoved inwardly and outwardly to set the watch, without admitting dust or water into the of the watch.

-t is within the province or the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

l Vith. the above and other objects in view which will appear as the description proceeds, the invention resides in the con'ibination and arrangement oi parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodin'ient of the invention herein disclosed, may e made within the scope of what is claimed, without departing from the spirit or the invention.

In the drawings Figure 1 shows in elevation, a portion of a watch whereunto the device forming the suhject matter of this application has been applied, parts appearing in section;

Figure 2 is a section on the line 22 of Figure 1, looking in the direction of the arrows, the crown and stem being omitted;

Figure 3 is a section on the line 22 of Figure 1, looking in the direction opposite to that indicated by the arrows, the crown and the stem being omitted;

Figure 1 is a section on the line 1l of Figure 1;

Figure is a view similar to Figure 1, but showing a slight modification.

The numeral 1 marks a watch case. The bow is shown at 2 and has an enlarged base 3 that is secured to the case 1. There is an opening 4 in the base 3. The how 2 has an inwardly projecting neck 5 in which there is a recess opening 6.

The crown is designated by the numeral 7 and includes an outer member 8 and an inner member 9. The outer member 8 has a projecting rim 10 within which its closely, a reduced part 11 on the member 9. A washer 12 is bound between the flat surfaces of the members 8 and 9 of the crown 7 and is located within the rim 10. The washer 12 may be made or" any suitable compressible material and has a central opening 22. A washer 14, likewise made or" any suitable material, and compressible, it desired, is interposed between the inner member 9 oi the crown 7 and the base 3 of the bow 2. The outer member 8 has a reduced journal 15 Serial No. 182,421.

defining a shoulder 16. The journal 15 is mounted to rotate in the recess 6 ot the neck 5, and the shoulder 16 abuts againstthe innor end of the neck 5. The bow 2 is stilt enough so tnat it cannot extend outwardly in ordinary use. The bow 2, however, has some resiliency, and tends to press the neck 5 the shoulder 16, to press the outer member 8 on the washer 12, to press the washer 12 against the member 9, to press the member 9 against the washer 1 1, and to press the washer 1 1 against the base 3 of the bow 2, the construction being such that dust, moisture, or water, cannot find its way into the crown 7.

The numeral 17 designates the stem of the watch. The stem 1? has a squared or polygonal end portion 18 that is received slidably, but against rotation, in an opening 19 formed in the outer member 8 of the crown 7. The stem 1'7 has a part 20 which is left-hand threaded in Figure 1, into the inner member 9 01" the crown 7, although, as shown at 21 in Figure 5, the cylindrical part of the stem may be right-hand threaded into the inner member 9 of the crown 7, depending upon whether the stem is to be moved outwardly or inwardly to set the watcln In Figure 5, parts hereinbe'tore described have been designated by numerals previouslyused, with the suliix a. The opening 22 in the washer 12 is large enough so that the squared part 18 ot the stem can turn therein, and in the washer 1e there is an opening 23 which is large enough so that either the threaded part 20 or the inner end of the stem 17, can turn therein.

The operator can hold the inner mom her 9 and rotate the outer member 8 to move the stem 1'? in one direction, and hold the outer member 8 and rotate the inner men,- her 9 to move the stem in an opposite direction, for the purpose of setting the watch. As has been explained hereinbefore, it will be practically impossible for dirt, moisture or the like to iind its way into the watch through the crown 7, because the parts ot the crown are held together by the resilient action of the bow 2, the stem being housed within the crown.

lVhat is claimed is 1. In a device or the class described, a crown comprising relatively rotatable members, a stem threaded into one off said members, means for mounting the stem in the other of said members for rotation therewith and for sliding movement therein, and resilient means for holding the rotatable members together with a constant pressure, the two aforesaid means cooperating to afford a watch pendant which is dust proof in both the setting position and the winding position.

2. In a device of the class described, a crown comprising relatively rotatable inner and outer members, a stem threaded into the inner of said members, means for mounting the stem in the outer of said members for rotation therewith and for sliding movement therein, and resilient means for holding the rotatable members together with a constant pressure, the two aforesaid means cooperating to afford a watch pendant which is dust proof in both the setting position and the winding position, said resilient means being a spring bow engaged with the outer rotatable member.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
